PRINTERS CHASE.

SPECEFICATION forming part of Letters Patent No. 304,605, dated September 2, 1884.

Application filed January 29, 1884.

.To @ZZ whom, t may concern-.-

Beit known that I, JOHN BRILL, of Milwaukee, in the county of Milwaukee, and in the State of Wisconsin, have invented certain new and useful Improvements in Printers Chases; and I do hereby declare that the following is a full, clear, and exact description thereof.

My invention relates to chases for printers use, and will be fully described hereinafter.

In the drawings, Figure l is a perspective view of my improved chase. Fig. 2 is a vertical longitudinal section through the center of one of the chase-sides, and Fig. 3 is a like section through the central brace of the same.

The object of my invention is to provide an improved chase which can readily be adjusted to lit type-forms of various sizes, and thus adapted to be conveniently used in place of n@ the assorted chases now necessary in printing establishments where a variety o1" jobwork has to be done. i

My adjustable chase consists of the four similar L-shaped pieces A, A, A2, and A3,

the parts a and b of which are made so as to slide respectively over and inside the parts b and a of each adjoining piece. For thislpurpose a double-dovetail-shaped groove, c, is

formed on the inner edge of the part a, to eX- tend from its outer end to within a slight distance from the angle it forms with the part b,

and through the center of the remaining solid angle end of said part a a longitudinal perforation, d, is made, wherein works the adjusting-bolt d. The outer end of the part b ismade in the shape of a double-dovetail tenon,

b, to correspond in length with and loosely lit in the groove c of the adjoining angle-piece,

a well-hole, e, to extend longitudinally along 4o the center or" said tenon b, and to correspond with the perforation d, made in the solid portion of the part a of the adjoining angle-piece.

A threaded nut, f, is embedded at a suitable point in the tenon b, so that its central open- I ing stands directly opposite the well-hole c, and is thus adapted to receive the threaded end of the bolt d. The angle-pieces A, A', A2, and Aa being put together by slipping the tenoned part b of each one int-o the groove c (No model.)

in the part c of each adjacent piece, the bolts d d are screwed in the nuts f f until the`desired size of chase has been obtained. The inner, upper, and lower edges of the parts a a are slightly beveled, and against said beveled edges rest the beveled laps di da, formed on the outer ends 'of the central cross-bar, D D. The piece D has a double-dovetail-shaped slot, g, opening in the inner end of said piece D, and extending along its center to a distance corresponding to the length of the grooves c 6o in the parts a ofthe chase-pieces. The piece D has its inner end formed as a double dovetail-tenon, d, of a length'to correspond and lit in the slot r/ of the piece D. rlhe central part of this tenon d has the vertical slot 7L to re- 65 ceive the body ofthe fastening-screw ,which passes through a holein the upper part of the slotted piece D, and screws in a threaded hole, i', in the lower part of the saine, whereby when this screw is tightened after adjustment ofthe parts D and D the arms of the part D, above and below the slot g, are respectively pressed down and drawn up against the tenen di* of the part D, thus making the cross-bar perfectly rigid, while by simply turning the screw in the opposite direction the pressure will be withdrawn from the said tenon dilwhich will then be free to move in and out of the slot g, (subject to the limits of its own slot h,) and thus permit any new adjustment of the chase desired.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

l. A chase for type-forms, consisting of four angle-pieces adapted to slide more or less into one another, and be maintained therein in ad justment, as desired, by means of screw-bolts, substantially as set forth.

2. In combination with an adjustable chase, an adjustable cross-bar consisting of two parts adapted to slide one upon the other, and to be secured at any desired adjustment by means of a set-screw, substantially as set forth.

3. The combination of the angle-pieces, each having a longitudinal groove and perforation in one part and a tenen on the other part, the said tenon being perforated longitudinally,

with the nuts f embedded in the said tenons, In testimony that I elaini the foregoing I and the screw-bolts d', substantially as set have hereunto set my hand, at Milwaukee7 in forth. the county of Milwaukee and State of Viseon- 4. In eoinbinationwith an adjustable chase, sin, in the presence of two witnesses.

5 the adjustable cross-bar formed of two parts,

D and D', one provided with a longitudinal JOHN BRILL. slot and vertical screw-holes, and the other with a tenon adapted to move therein, the said Witnesses:

tenon having avertioal slot7 and the seeuring- II. G. UNDERwooD, 1o screw i), adapted to work in said slot, substan- A. C. PLEYTE.

tially as set forth.
